EAVES-TROUGH.

SPECIFICATION forming part of Letters Patent No. 531,044, dated December18, 1894.

' Application filed November 20,1893. fierial no; 491,377. (ModeL) ToaZZ- whom it may concern:

'Be it known that I, ALVIN O. KANNEBERG, a citizen of the United States,and a resident of Canton, county of Stark, State of Ohio, have inventeda new and useful Improvement in Eaves-Troughs, of which the following isa full, clear,'and exact description, reference being had to theaccompanying drawings, making part of this specification.

My invention relates to an improvement in caves troughs, and consists ofcertain features of construction and combination of parts as will behereinafter described and pointed out in the claim.

The object of the invention is to provide in eaves troughs, a slip jointthat is economical and durable, whereby troughs of any desired lengthmay be erected without solder or tools of any special character, theparts adapted one to receive the other freely, and

to form a joint not liable to leak.

Figure 1, of the drawings is a plan viewof a fragment plate or sheet,from which a section of trough is made, showing the form of the endportion. Fig. 2, is a similar view showing the first bend in process offorming the slide or groove; Fig. 3, a similar view showing the secondbend or operation. Fig. 4, is a perspective showing the sheet turnedinto the form of trough semicircle in cross section. Fig. 5, is asimilar View showing the roll formed on the edge of the trough, and theslide or groove for slip joint complete. Fig. 6, is a similar View ofcompleted joint as formed between two sections. Fig. 7, is a transversesectional view on line X X, Fig. 6..

Referring to Fig. 1, A represents the end portion of a sheet of metal,having a portion cut away as shown, reducing the width of the endportion from w to x, to form anarrow lap portion B, and a shoulder 0.There is also a portion cut-away at the side, extending from y to theshoulder O. The corner of the lap B is cut away or rounded as shown ata. The outer corner of the shoulder C is also cut away and rounded asshown at B. The object sought in rounding the point a b, will be morefully described farther on.

To form the groove to receive the end of the trough A as shown in Fig.6, the lap is turned back on the plateA as shown in Fig. 2. The endportion is then folded back on itself, as shown in Fig. 3, thus formingthe groove 0 and the projected end portion (1.

The sheet isnow turned to semicircle form as shown in Fig. 4, afterwhich is formed the roll e as shown in Figs. 5 and 6. In forming thisroll, the edge of the sheet between the points a: and w, is at the sametime bent in a roll concentric to the roll e, between which rolls, theroll of the section a fits, thus greatly strengthening the joint, aswell as increasing the friction between the two sections of the trough,whereby the tendency of the sections to pull apart, is reduced and amore perfect water tight joint secured. The object of the roundedportions or and b as now shown, serve a very important purpose; that offorming guides by which the roll a of troughsection A is guided into theroll 6 of trough section A. The end of the section A, resting on theextension cl will be directed into the groove 0 as shown in Fig. 6,which may be readily and quickly accomplished when constructed ashereinbefore described.

I am aware of the patents granted to Bowers and Dickelman and Bonkrake,dated and numbered respectively, November 7, 1893, No. 508,366, andNovember 1, 1892,No.4.85,573, and wish to be understood as not claimingthe construction therein shown. It will be noticed that neither of thesepatents show the edge-of the sheet from which they make the troughcurved concentric with the roll, but on the other hand, terminate theedge below the roll.

Having thus fully described the nature and object of my invention, whatI claim is As a new article of manufacture, an eaves trough having oneedge of one of itsends cut away from x to ac, forming a tongue B and 7cut away from O to y, and having rounded shoulders a and b, recedingfrom the front end of the trough the-tongue B being folded back upon thetrough from the shoulder b, thence forward upon itself to form a grooveor pocket 0, and extension d, and its edge from m to :r, bent laterallyinto a roll, the edge of the trough beingbent over the tongue, to form aroll concentric with the aforesaid roll, substantially as shown anddescribed.

In testimony whereof I have hereunto set my hand this 15th day ofNovember, A. D. 1893. 1
